Data Coverage

The RATPAC data come from 85 stations with near-global coverage, whose locations are shown on the station map (new window) and included in the station list. The data are provided on 13 atmospheric pressure levels: the surface, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50 and 30 mb. Where available, data begin in 1958 and extend through the present. Some of the 85 stations have discontinued observations since the 1990s, and not all stations have observations at all levels.
